That is the original ending, the test audiences laughed very much while seeing it so they decided to change it, but there was no more budget and the actors refused to come back for free. So they made the shark explode and mix it with the rest of the footage they had.

Watched that clip and laughed until it hurted. Yes, that ending is just terrible, prehaps even worse than the exploding shark. However, I am willing to buy it more since it makes a bit more sense now than the shark just exploding. At least I know why the boat sinked and everyone got into the water.

OK, the strange thing about this for me is that I've always remembered the ending as them skewering the shark, and the boat sinking. It was not until I purchased the DVD that I saw the current, awkward boom-boom shark finale. One of the VHS or LD releases must have had the original ending.

i have a daughter who LOVES sharks.(the real kind...and lots of documentaries that are very well made)However, as per an obsession, we also watch ANY movie with sharks.I can tell you all this: in b movies, SHARKS ROAR!haha!check it out. all the good bad movies have roaring sharks, so much so that it is not complete unless the shark roars for us.

OMG, Bruce the Shark's rubber skin really took a puncturing with that clip! I don't know whether that facial expression was Lorraine Gary's good acting or her sheer disbelief at that roaring contraption. They should have let Bruce stay broken like he was in the first film so they could have had those POV shots again.
